This has been my long standing PSpice guide for
many years now. Provides a
"tutorial approach" to using PSpice through graduated examples.
This is a netlist based book, a great reference covering the all the basics.
The cover claims a best-selling guide (I'm not surprised), a great starter
on SPICE.

Vladimirescu, one of SPICE's original developers,
not only gives the novice a great introduction, but dives in deep for the
more experienced user. Lot's of examples with some advanced circuits as
well. I really enjoyed the SPICE algorithms explained in detail. You also
get a nice SPICE history lesson and some insight on analog behavioral
modeling and convergence.

The Art of Electronics
I recommend this book as the electronics book to have on your shelf.
Covers analog and digital design, a broad reference of circuits from various
areas. A great nuts and bolts approach to circuit design that emphasizes
intuitive understanding over mathematics. An excellent companion to an
engineering text. The informal style takes the stuffiness out of theory and
puts some fun back into it.

Microelectronic Circuits
Here's an engineering text that covers the essential analog and digital
concepts. This 4th edition says its one of the most widely accepted texts
for teaching. Op amps, discrete semiconductors, feedback theory, filters,
digital gates and memory devices are covered. Clear explanations without
losing the full engineering theory. This book along with the Art of
Electronics have made the perfect resource pair for me.

Another classic book that seems to
give you security just having it on your shelf. Covers basic op amp theory in
excellent detail. But, like the title says, its more cookbook than theory.
However, with over 200 practical circuit
applications, its an awesome collection of op amp circuits to have on hand.
